Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82018, here are decompositions:
- 5 + 82013 = 82018
- 11 + 82007 = 82018
- 47 + 81971 = 82018
- 89 + 81929 = 82018
- 149 + 81869 = 82018
- 179 + 81839 = 82018
- 257 + 81761 = 82018
- 269 + 81749 = 82018
Showing the first eight; more decompositions exist.
